99 Health Q&A Experts introduced that the unable to fertility caused by the obstruction of the vasters is a common phenomenon in clinical practice.Sperm discharge must be output small tubes, epididymia, vasia, ejaculation pipes and part of the urethra by testicular output.The blockage of any of the above can affect the discharge of sperm.If the unilateral vascular vascular blocking the male reproductive system, the impact on fertility is not great. If bilateral obstruction and sperm cannot be discharged normally, it will cause infertility.About 7.4%of male infertility is blocked, while more than 40%of sperm -free.Therefore, the blockage of vasters is one of the common causes of male infertility.
Urinary surgery experts introduce the causes of the blocked tubular blockage:
1. Congenital malformations: such as epididymal head, question, and tail section, such as a section or completely missing, vastered pipes are not connected to epididymia, an epididymal, vascular or seminal vesicles are inaccurate.
2. Speed and chronic inflammation of the reproductive system: the most common and important reason for the purple plug of the vollar tube.Common combination of oxytopiacitis, seminal vesiculitis, or epididymal vasters.Due to the existence of inflammatory secretions or the destruction of the tissue microstructure, and the scar tissue caused by the healing of inflammation, it can cause poor infusion.
3. Damage: If the scrotum or vinion trauma can damage the epididymal and the vascular tube, the scar formation after the healing of the trauma can also cause changes in the structure of the autonomic pipeline, which affects the transmission of sperm.
4. Tumor: Nature and malignant tumors and suppeble creatures of reproductive systems and its neighboring tissues, or directly block the severing tubes, or obstruct it by compression but fine roads.
